I on. BURNER.

Application filed April: as, 1924, Serial No. 708,543. Renewed March 28, 1925.

To all whom it may concern:

Be. it known that we, F map F. UHL and HEBER J. UHL, citizens of the United States, residing at Bartlesville, in the county of WVashington and State of Oklahoma,.have

invented new and useful Improvements in Oil Burners, of which the following is a specification.

and contemplates a construction of high'efliciency with the consumption of a minimum amount of fuel.

An object of the invention is to provide a connected oil burner that is capable of being easily installed in places where the.

of controlling or regulating the air to cause a quicker generation and consumption than in other types of oil burners.

The nature and advantages of the invention will be better understood when the following detailed description isread in connection with the accompanying drawing, the invention residing in the construction, combination and arrangement of parts as claimed.

In the drawing forming part of this application, like numerals of reference indicate similar parts in the several views, and

wherein Figure 1 is a vertical sectional view through the burner forming the subject matter of the present invention.

Figure 2 is a top plan view.

Referring to the drawing in detail, 10 representsthe bottom of the burner which consists of a double wall casing, the inner and outer walls 11 and 12 respectively being arranged in spaced concentric relation as clearly illustrated. Rising from the bottom 10 of this casing is a plurality of 11p rights 13 which supports a trough 14 into which the oil and air is conveyed and subsequently burned. It will be noted that this trough 14 is wholly disposed within the confines of the inner wall 11, being circular in plan and spaced from the centrally arranged tubular .member 15, which defines an air intake chamber. This tubular member is open at the bottom and top thereof, for'the amount of air which of course enters the bottom, and passes out of thetop of said member into the trough 14. The trough is further supplied with air from the space between the inner and outer walls 11 and 12 respectively, the bottom 10 being provided with a circular series of openings 16 for this purpose; The outer wall '12 is also considerably higher than the inner wall 11, and has its upper edge curved inwardly and downwardly as at 17, terminating at a point directly above but in spaced relation to'the trough 14. Consequently, the air entering the openings 16 passes upwardly in the space between these walls, striking the curved wall, which serves to deflect the air into the flame and trough 14.

The amount of oil conveyed to the trough 14 is regulated by a valve 18 which is sup:

ported adjacent one end of avertically disposed rodl9 which passes through'a sleeve 20. Secured to the upper end of this rod 19 and reposing upon the valve'18 is one of a pair of heat plates 21 and 22 respectively, both of which plates are of substantiall inverted saucer shape. The plate 21 is a justable toward and away from its 00- operating plate 22 incident to the adjustment of the valve 18 as both of these parts are supported by the rod 19 as clearly illustrated in Figure 1. The other plate 22 is formed with a collar 23 which is threaded upon the upper end of the stem 20, and further provided with a central opening through which the oil passes as it leaves the sleeve 20. The edge of this opening just referred to constitutes a valve seat for the valve 18, and this seat is indicated at 24. The rod 19 may be adjusted in any suitable manner, preferably in the manner to be hereinafter described, but it is manifest, that by adjusting the valve 18 with relation to its seat, the quantity of oil admitted to flow into the trough 14 can be conveniently.

, ly disposed tubular member also strikes against the lowermost heatin plate 22 which serves to deflect the air into the trough 14, and this fact coupled with the fact that the oil conveyed to said trough passes between the heating plates, both the air and oil are heated before reaching the trough. The tubular member 15 is supported upon the sleeve 20 by supporting elements indicated at 25. Rising from the lowermost heating plate 22'is a plurality of pins 26 which pass through openings formed in the adjustable plate 21, these pins serving to guide the last mentioned plate in its vmovement toward and away from the fixed plate 21, and also center the plates to provide for an equal distribution of oil in all directions, and thereby causing an equal flame all around the trough '14. The pins also prevent any possibility of turning movement of the plate 21 incident to the rotation of the rod19 which takes place for the purpose of adjusting the valve 18 with relation to its seat.

The sleeve 20 above. referred to, has its lower end associated with a coupling 27,. which coupling is formed with a branch 28 coupled to the adjacent end of an inlet pipe 29, which in turn communicates with an oil supply pipe 30 through a coupling 31. "The inlet pipe 29 is coupled by a sleeve 32 to one end of asolid block coupling 33, the

other end of which is threaded into the branch 38 of the coupling 27, but it will be noted that the solid block coupling 33 is provided with a series of longitudinal bores 34 through which the oil flows, from the pipe 29 into the sleeve 20, and subsequently forced through this sleeve under pressure through the course above described "util it reaches the trough 14. *This solid block coupling 33 also constitutesa bearing for a shaft 35 which is arranged within the inlet pipe 29, and Which shaft is equipped at one end with a hand wheel 36 through the instrumentality of which the shaft is rotated to control the valve 18 above referred to. The inner end of the shaft 35 supports a bevelled gear 37 which meshes with a similar gear 38 formed with a nut 40 which is threaded on the lower threaded extremity 41 of the valve operating rod 19. Consequently when the shaft-35 is rotated in one direction, rotary motion is imparted to the bevelled gear 19 in a direction to elevate the valve 18 and when rotated in a reverse direction lowers the valve 18. The coupling 27 is also provided with a pocket or depres sion 42 in align with the rod 19 to allow the rod to moveyerticallywithin the sleeve 20. Furthermore, the coupling 27 is formed with a shoulder 43 upon which the nut 40 forming part of the bevelled gear 39 reposes.

In practice, an as'bestos wick 44 is first pare'nt,,we desire to have it understoo located tubular member 15, and also throug 1- the series of openings 16, and is thus conveyed through the trough on opposite sides thereof giving a circular flame. Depending from the bottom 10 of the casing is a small coupling 45 to which a small pipe (not shown) maybe attached, which pipe is util- ,ized to carry off the surplus oil in event that the fire or burner should 0 out for any reason. Furthermore, a pi ot li ht-is arranged within the casing and ind cated at 46. Manifestly, the burner can be operated and controlled by anyone, for instance 1 asmall child if used for domestic purposes,

and as above stated, it possesses'maxlmum. efficiency wltha minimum consumpt on of The trou h 14 can also be quickly fuel.

removed from t e casin when it is necessary to clean'or repair t e trou h, and this i can be easily accomplished by rst removing the heating plates 21 and 22. Again, the solid coupling 33 provides for an ad justment between the gears 37 and 39 to p compensate for wear between these parts. While it is believed that from the foregoing description, the nature and advantages of the invention will be readil that we do not limit ourselvesto what is herein shown and described, and that such chan as may be resorted to when desired as all within the scope of what is claimed.

Having thus described the invention,v we claim:
